Even though the Sprint Nexus S 4G sports the ‘Nexus’ branding from Google, it took nearly 4 months for the official Ice Cream Sandwich update to be available for the phone. Thanks to some proprietary WiMAX and CDMA files, the Nexus S 4G was not supported by AOSP (Android Open Source Project). The same stands true for Verizon’s Galaxy Nexus, as Google had clarified earlier this year.
We’ve been able to resolve the issues around Nexus S 4G, and we can now properly distribute its CDMA and WiMAX binaries. That allows Nexus S 4G to work with AOSP just as well as Nexus S.
As a result, we now consider Nexus S 4G to be fully supported in AOSP, with no restrictions. Overall, Nexus S is the preferred platform for AOSP work.
Earlier today, Jean-Baptiste Queru announced that henceforth the Nexus S 4G will be “fully supported in AOSP, with no restrictions”. This means that whenever Google pushed the Jelly Bean source code to AOSP, it will just be a matter of time before fully functional stock Android 4.1 ROMs show up for the handset. No need to wait for Sprint to push the OTA update, if you are comfortable using adb and/or fastboot. This move from Google will definitely be appreciated by a lot of Nexus S 4G owners, who had to wait frustratingly long for the Ice Cream Sandwich update to be available for their phone.
In regards to the Verizon’s Galaxy Nexus being supported by AOSP, Jean said that there are still a lot of proprietary files of GPS, Camera and NFC that break AOSP support for the device. Bad luck VZW Nexus owners!
